Heh, my LFS says that with one exception (which was not the Seaclone), all the skimmers that he's used work. Some are a bit more finicky than others.
He recommended a Prizm Pro, which he has on his show tank. On the basis of various internet equipment reviews (to be fair, they were comparing the Prizm regular with the Remora regular), I went with the Remora Pro (also bought from LFS, but for slightly more than the Prizm Pro).
